PUMPING APPARATUS.

Specification of Letters Patent.

Application filed November 18, 1908.

Patented Jan. 26, 1909.

Serial No. 463,204.

To all whom it may concern:

Be it known that I, SULLIVAN W. EDMIS- ToN, of Hillsboro, in the county of Highland and State of Ohio, have invented certain new and useful Improvements in Pumping A paratus; and I hereby declare that the fo lowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improved apparatus for pumping water from wells and cisterns, and is designed to be operated by the weight of the animals or fowls when they come to the well for water.

The objects of the invention are to enable the animal to automatically pump its own drinking water to economize the water by preventing waste thereof; to return unused water, if desired, back to the cistern or well; to filter such water before it is returned into the well; to regulate the amount of water pumped according to the size and weight of the animal; and to enable small fowls to be supplied with water; and to prevent the water troughs and receptacles freezing in cold weather.

The invention will now be described with reference to the accompanying drawings, in which Figure 1 is a side elevation of the complete apparatus, showing it partly in section, and applied to a well; also showing the parts in raised or non-watering position, in full lines; and in lowered, water-supplying position, in dotted lines. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is an enlarged cross section of the trough on line 3-3, Fig. 1. Fig. 4 is an enlarged detail section of the stationary water-receptacle. Fig. 5 is a detail sectional view of the rear end of the water trough.

The apparatus comprises a pump-chamber 1, located in the well or cistern W, below the water level, and having a plunger 1"= connected to a piston rod 1". Said plunger is provided with a valve 1, adapted to open when the plunger rises, and close when the plunger lowers. The chamber 1 is connected below the plunger with a pipe 1 which extends up above the well and is arranged to discharge into a trough 2 of peculiar construction. This trough 2 is preferably made of metal, and with double walls, the space between the walls forming a hotair chamber, which can be heated by a lamp L, that can be placed in the hollow end of the trough through a door 2 in the outer wall thereof, as indicated in the drawings. The lamp is used in cold weather so as to keep the sides of the trough suiiiciently warm to prevent the water freezing thereon.

The receiving end of the trough is provided with a discharge spout 2, which enters a re turn pipe 3, that leads into a filter 3*, which in turn discharges into the well, so that water not used will be returned from the trough filtered and discharged into the well, if desired.

The filter may be of any suitable construction. The outer end of the trough 2 is suspended by links 2 from a cross piece 4*, attached to an overhead lever 4, which is pivoted by a bolt 5' on an upright 5 beside the well. The plunger rod 1 is also pivotally connected by a bolt 4 to the lever 4. The rod 1 may have a series of holes 1 in its upper end, with either of which bolts 4 can be engaged, thus providing an adjustment for the plunger rod. Similarly the upright 5 may be provided with a series of holes 5 with any of which the bolt 4 may be engaged, to vary the point of connection of the lever 4 thereto. The links 2 may be connected to cross piece 4* by bolts 2 that can be engaged with any one of a series of holes 2 in the links to vary the normal inclination of the trough.

The trough 2 is preferably provided with lateral branches 2*, which wil allow several animals to drink at the same time, these branches being preferably double walled, (so as to be ke t warm by lamp L also), and are slightly inc ined so that when the trough is raised, as indicated in full lines in Fig. 1, all the water therein will drain back to pipe 2. The trough furthermore is provided with a pipe 2 which can be opened if desired, so as to allow water to esca e from the trough into a receptacle 9, place beneath the trough, and forming a convenient watering place for small stock and fowls. This receptacle is preferably double-walled, and may also be heated in cold weather by a lamp L placed therein as indicated in the drawings, so that it will not freeze. A platform 6 is arranged beside the trou h, as shown, and is pivoted at 6 at one side, and its other side is suspended by links 6 from the end of lever 4, links 6 being connected to lever 4 by a bolt 6 which can be engaged with any one of a series of holes 6 in said links, to vary the inclination of said platform. The other end of lever 4 is weighted, as at 4 in any suitable manner, so as to slightly more than counterbalance the weight of the suspended portions of the trough, platform and plunger, so that normally these parts are upheld in the position shown in full lines in Fig. 1, so that the trough will empty itself. But if an animal comes onto the platform 6, its weight overcomes that of weight 4 and the parts descend to the position indicated in dotted lines in Fig. 1. The descent of the plunger in the pump-chamber causes water to flow out of pipe 1 into the trough 2, and supply the animal with sufficient Water to slake its thirst. The larger the animal the greater the amount of water raised. When the animal leaves the platform, the weight 4 again raises the parts to the position shown in Fig. 1, in full lines, and the water flows back to the filter and well; or it may be permitted to pass through pipe 2 into the receptacle 9.

In order to regulate the supply of water spring 7 may be used to resist the movement of lever 4 beyond a certain point in the pumping operation. I have shown a compression spring 7, confined between loops 7 7 the former of which is connected by a link 7 C to lever 4, at the side adjacent the weight 4", and the other link 7 is attached to upright 5. The spring 7 is so adjusted and connected to the upright and lever that if but one animal comes onto the platform 6, it will actuate lever 4 sufficient to deliver enough water to satisfy it; if now another animal comes upon the platform the lever will be further depressed, against the resistance of spring 8; and if still another animal comes onto the platform the lever will be still further depressed. By this means I regulate the amount of water pumped, approximately according to the size and wants of the animal, or animals, coming onto the platform and thus prevent waste.

If desired a cable 8 may be attached to lever 4, and led over suitable guide pulleys 8 to any desired oint, ,where it may be provided with a pul or lever 8 so that a person can operate the pump from a distance by pulling on the cable, when no fowl or animal is on the platform. If desired the water can be carried from receptacle 9, through suitable pipes 9 to any desired point. Or any overflow therefrom can be discharged back into the filter 3 by pipe 9. If desired the pipe 1 may be provided with a valve 1 and a pipe 1 connected with pipe 1 below valve 1 and provided with a valve 1 By closing valve 1 and opening valve 1 Water can be forced through pipe 1 to any oint desired when the pump is operated.

y closin valve 1 and opening valve 1 the watelr will be delivered into the trough as usua Having described my invention what I desire to secure by Letters Patent thereon is:
